the Logitech V270 is good but i wouldn't say it's a great gaming mouse.

the Apple BT Mighty Mouse has gotten good reviews by people who game as well as general day-to-day tasks. that said, it is not for everyone. definitely check out the feel at an Apple Store before buying.

Logitech makes some pretty complex mice that are not BT but are great for gaming.

I have a Logitech v270 for my 15.2" final gen Powerbook.
Its a great general purpose mouse, but there are times it lags or loses connection.
But for me, I wouldnt give it up for anything right now..
Im a grad student and spend lots fo time online researching articles and writing papers.

(on my off time I use the trackpad while sitting on the sofa with a beverage, my spouse and 2 greyhounds)

And I love the fact that the V270 has an on/off button and it uses regular AA batteries. I keep a pile of AA rechargables for my misc. gadgets.
Not having to maintain a seperate charger or another damn cable to charge it is sweet.

I think its the batteries.
It'll only lose connection for a second or so.
It comes back rather quickly.
I'll happen maybe twice a week at the most.
Your milage may vary. Again Im using the v270 on a Powerbook. Using it on a Macbook may not have this problem
